IR8 Question 10 Refunds and/or transfers
If you’re entitled to a refund you can:
transfer it to arrears that are being paid off
transfer all or part of it to your 2020 provisional tax
have it direct credited to a bank or other deposit account, for example, a building society account.
If you’ve made payments towards your 2020 provisional tax and, after completing this return, find you have less or no provisional tax to pay, the overpayment can be included in the amount we refund or transfer. Print the overpaid amount in Box 10A.
